Hey Kgr, if like me it took years to get to the point of quitting, it's going to take a bit longer than a week, 5 days is still early days, give it more time!!
The body needs to adjust physically, mentally and emotionally, we need time to build a new life, for me I didn't even know what life I was seeking to build for a long time, so of course you're going to feel uneasy, I didn't know anything other than drinking when I quit and so I had to rebuild my life from scratch, but it can be done!!
Hang in there, you can do this!!
